Haha, that was fun. I was too modest. My porous rock, the size of the Empire State building landed in water and barely caused a ripple. Diet Tsunami. I just don't have enough evil in me to calculate the end of earth.

The Earth is completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.
100 percent of the Earth is melted

The crater opened in the water has a diameter of 1520000000000 km ( = 946000000000 miles ).
For the crater formed in the seafloor:
Transient Crater Diameter: 931000000000 km ( = 578000000000 miles )
Transient Crater Depth: 329000000000 km ( = 205000000000 miles )
Final Crater Diameter: 33700000000000 km ( = 20900000000000 miles )
Final Crater Depth: 3490 km ( = 2170 miles )
The crater formed is a complex crater.
